To use the Guestbook module, there probably will be some tuning required (see forums) to be able to use it with the Captcha module to avoid spam, and the Spam module with custom filters to avoid hostile entries. Plus I have to see if the guestbook module allows a general guest book or only a per-user guestbook, in which case only user Heritage would have a guestbook.

The newsitem_timeline url should give the ful;l news listing on its own, and when a category id is appended to the url, then it should list news for that category. This is how I wanted to make timelines for different people. However, this cid functionality doesn't seem to be working, maybe because path is turned on and there was some pathauto entries in the path module before pathauto was disabled. Maybe this will work better once the taxonomy wrapper is installed and I use the views taxonomy filters instead of the manually added category functionality which doesn't work well in views filters.

I have installed and enabled the Related links modules for certain node types. Related links blocks should show up on the right column for affected nodes. Related links can be manually entered in the Related links field when entering a node by adding a path and a tittle for each link. Related links should also get automatically discovered, but for this feature, I don't know if anything but the body is considered. I know it supports taxonomy, but I don't know if it supports Category, multiple category, or title, so not a lot of related links are automatically showing up at the moment. We need to keep an eye on this feature to see if it is useful and worth keeping.

This is not implemented in the current category module, but the code here seems to work for drupal5, so I modified category.inc according to: http://drupal.org/node/85984 Once the database cache refreshes, the category filters should appear on the views edit page.
